* New LLVM tools:
- llvm-debuginfod-find: Tool to fetch debuginfod artifacts.
- llvm-tli-checker: LLVM TargetLibraryInfo versus SDK checker.
* New Clang tools:
- clang-linker-wrapper: A wrapper utility over the host linker.
- clang-nvlink-wrapper: A wrapper tool over nvlink program.
- Add clang-repl-private-deps.patch to make link dependencies of
clang-repl private, otherwise CMake can't install.
- Add PPCISelLowering-Avoid-emitting-calls-to-__multi3.patch to
fix build on PowerPC (32-bit).
- Drop llvm-exegesis-link-dylib.patch, instead we don't build
llvm-exegesis anymore and add check-no-llvm-exegesis.patch to
disable the corresponding tests.
- Rebase patches:
* lldb-cmake.patch
* llvm-do-not-install-static-libraries.patch
* lvm-normally-versioned-libllvm.patch
- Drop patches that have landed upstream:
* llvm-update-extract-section-script.patch

Better detect 64bit atomics support.
|
|
|
|
It appears that on i586 std::atomic<uint64_t>::load is compiled into
|
|
instruction, but std::atomic<double>::load uses __atomic_load_8. This must
|
|
be detected so the build system links it to libatomic.
